Application filed .Tune 27, 1912. Serial No. 706,189.

TocZl 'whom t may concern Be it known that l, SAMUEL E. Sunni-ir, a citizen ol the United States, and resident of `Ni-aodlniven, borough of Queens, countyof Queens, city and State of' New York, have invented certain new and useful improvements in Slug-Ejectmg Devices for Line- Casting Machines, of which the Jf'ollowing isa speciieatlon.

'.l` his invention relates to improvements in machines in .which printing slugs are cast in a suitable mold and are delivered or dis-l charged therefrom .by means of' an ejector which is adapted to be advanced from the rear through the mold and to engage the printing slug or bar on its bottom edge. ln

vmachines oirthwis type the molds are adjusttype bar, and to provide simple and ellicient means by means of which the ejector blade of the proper width may be brought into register with the line `mold and into cooperativo relation with a horizontally reciprocating slide or pusher bar.

Another object ot the invention is to pro- -vide a series of ejector blades arranged in parallel relation and of dii'l'ercnt widths and to so mount said series of blades that they may be readily shifted transversely to the line of movement of the main slide or pusher bar to bring the selected ejector blade into cooperative relation with said slide and in register with the line mold.

A further object of the invention'is to provide a series of ejector blades of different widths, and means whereby the ejector of the desired width may be selected and brought into register with the line mold and into cooperative relation with the ejector blade operating mechanism. i

There are other important objects and vantages of the invention which will' appear hereinafter.

ln the drawings, Figure 1 is a sectional View showing a portion of the ordinary mold wheel, knife block, mold slide, and eooperatingparts, of a linotype machine of the Mergenthaler type, showing my inven- Speeicaton of Letters Patent.

tion applied thereto; Fig. 2 a sectional View on the line II-H of Fig. 1, looking in the direction of the arrows; Fig. 3 a detail plan View of theejector blade case and thel means for shifting it laterally; Fig. 4 a front view ofthe 'ejector blade ease and its shifting frame; and Fig. 5 a side elevation thereof. Fig. 6 is a. side elevation of the main slide and one ejector blade connected therewith.

Referring to the various parts by numer als, l designates the mold wheel or carrier having the usual slot .2 which receives the mold 3. l

4 designates the knife block which is arranged in front of the mold and carries the usual slug trimming knives 5.

G designates the usual .main slide or guide in which the usual ejector blade of the ordi nary Mergenthaler linotype machine I is guided in its slug ejecting movements.

In the main slide 'or guide is arranged an ejector blade case 7, said case consisting ci `the upper and lower plates andthe side plates 9, the trontof said case being open, as indicated clearly in Fig. 4. n this case arearranged a number of ejector blades 10, said blades being odifferent, widths and corresponding to the variations in the lengths of type bars or slugs which the machine is adapted to cast. These ejector blades are arrangedl close together 1n parallel relation and in regularly increasing` widths, so that the smallest o'r narrowest ejector blade lies against one side plate 9 andthe largest or widest ejector blade lies against the other side plate 9, as indicated clearly in Fig. 4 of the drawing. To hold the free forward ends yoi the ejector blades in their proper relative positions and to guide them in their reciprocating movements, a stepped iller piece 10a is secured in the forward end of the ejector blade case. It will be noted that this stepped filler piece engages the 'upperedge `or" each ejector blade at the forward end Vthereof when the blades are in their normal retracted 'position, and that it forms a guidefor said blade and prevents 'its forward end lifting or movingupwardly, so that the ejector will be accurately? guided `to -the mold. The top and bottom plates 8 of the ejector blade case are each provided with a 'pair' of parallel, transyersely arranged, oblique grooves v11., as shown clearly A3. ,The forward una end of this case is open and said caseis adjustable or movable backvvardly in the main slide or guide to bring any one of the ejector blades into register with the mold opening so that the selected ejector may be moved through the mold to eject the slug. As a simple means for accomplishing this sideivise adjustment or movement of the ejector blade case, I provide a reciprocating frame 12, 'the upperA and lower bars 13 of which extend over the bars 8 of the ejector case. The bars 13 of the shifting frame are each provided u'ithtwo projectionsjl: which enter the slots 11 of the adjoining bar of the ejector case. Each of these bars 13 is also provided with a long vertical rib 15 which lits and slides in a corresponding groove 1G in the upper and lower Walls of the main guide 6. It is manifest that by moving the shifting frame 12 :forwardly and rearwardly the ejector case Will be moved laterally through the medium of the projections 111 and the cam slots 11 in which they iit.

To move the ejector case I connect to the shifting frame a lever 17 and provide means for-locking said lever in its various positions, said means' consisting of the bracket 18 having a series of holes therein and a locking pin 19 adapted to be passed through the lever in any one of said series of holes. By moving the rlever the ejector blade of the proper width may be brought into register with the mold opening andmay be then locked by inserting the pin 19 through the lever and the registering hole in the bracket 18.

To operate the ejector blades I provide the main slide or push bar 20 which is operated by means of the usual pitman .21 c0nnectedto the head block 22. rThe forward end of themain slide or push bar enters the rear end of the ejector blade case and is provided at its lower edge with an upturned hook Q3. rIhis main slide or push bar is of the same thickness as the ejector' blades, and

each ejector blade at its rear lower corner is.

provided with a slot or recess 24 of the same shape as the hook 23 of the main push bar. These slots or recesses are so arranged that they register with the coperating hook on the main slide. The main slide or push bar is directly in line with the mold slot and is maintained permanently in that relation. By shifting the ejector blade'case or holder laterally through the medium of a lever 1T the desired ejector blade is brought -into line with the main slide so that the hook 9.3 on said slide its in the recess 24 of aoselected blade. The selected blade and the main slide are then interlocked in operative relation, the interlocked blade being directly in line with the slot in -the mold. It is manifest, therefore, that by forcing orward the main slide the ejector blade is' c`arried for- Ward to force out the cast slug or type bar,

messi/t as indicated in dotted lines at Q5 in Fig. 1. Whenthe main slide is returned to its normal position the ejector blade is returned to its normal position ivithin the ejector blade ease by reasonol'the hook Q3 being interlocked in the recess il of the blade.

The bar 1.6 serves as a guide for the push bar 2O and also closes the inner end of the ejector blade case when the same is thrown laterally out of the frame 12 by the lever 17. It manifest that this case must be open at its inner end to receive the main slide 20.

The advantage of having a solid or onepiece ejector blade is manifest. Its operation is positivo and accurate and it is practically impossible for the mechanism to become jammed or inoperative. It is to be understoothof course, that the ejector blades are thin so that a suitable number of them may be ararnged within the ejector blade caseivithout making the case too thick to be conveniently arranged Within the main guide. It is also manifest that the lateral or sidewise movement .of -the ejector case need be very slight, and yet permit of the use of a considerable number of ejector blades.

It is, of course, to be understood that the I means for laterally shiftingethe ejector case may be varied, and I do not wish to be limited i'n this respect.
